Abstract

The utility model provides a combustion-supporting device for a coal-fired boiler, which is matched with a large coal-fired boiler, wherein one or two water tanks are arranged in housing, the upper part of one side of the water tank is connected with an exhaust pipe through an exhaust solenoid valve , the lower part is connected with a water inlet pipe through a water inlet solenoid valve and a check valve, the other side of the water tank is communicated with an oxyhydrogen generator protruding from the outer surface of the housing through an upper connecting pipe and a lower connecting pipe respectively, a safety valve is arranged on the upper connection pipe, and a combustion-supporting device formed by an electric cabinet is fixed on the housing. The catalytic medium in the oxyhydrogen generator conducts catalytic action with the help of the furnace temperature and quickly decomposes water into hydrogen and oxygen, and the hydrogen and the oxygen are directly jetted into the combustion chamber to participate in the combustion, so that the combustion chamber temperature is remarkably improved, the staying time of the smoke and dust in the furnace is obviously prolonged, the fuel and the combustible matter in the smoke and dust can sufficiently burn, the fuel resource is effectively saved, the heat efficiency is greatly improved, and the dust emission is remarkably reduced. The utility model also has the advantages of compact and reasonable structural design, reliable and stable working performance, automatic control, convenient use, energy conservation, environmental protection, economy and practicability, and is suitable for extensive application in the industry.

Description

The coal-burning boiler combustion-supporting

Technical field: the utility model relates to a kind of auxiliary combustion equipment, particularly relates to a kind of and the matching used auxiliary combustion equipment of large coal-fired boiler.

Background technology: large coal-fired boiler is the indispensable combustion apparatus of concentrated supply of heating in the city and industrial production, for making fuel combustion abundant, air feed and blower unit generally all are installed, and increase huge investment in order to reduce being emitted on of flue dust to add cleaner in the flue.However, still have a large amount of carbon granules, tar to fail fully to burn in the existing boiler, materials such as alkanes and sulfur dioxide enter atmosphere, not only environment are caused severe contamination, and directly influence boiler thermal output.

Summary of the invention: the purpose of this utility model is for a kind of coal-burning boiler combustion-supporting is provided, mainly solve existing fire coal boiler fume outlet and still have a large amount of carbon granules, tar to fail fully to burn, materials such as alkanes and sulfur dioxide enter the atmosphere pollution environment and influence the problem of boiler thermal output.

The technical solution of the utility model is as described below: this utility model comprises housing, water tank, electric cabinet, tube connector, magnetic valve, safety valve, check-valves, water inlet pipe and blast pipe, it is by being provided with one or two by establishing water tank in the housing, above water tank one side, be connected with blast pipe through exhaust solenoid valve, the below is through entering water electromagnetic valve, check-valves is connected with water inlet pipe, the water tank opposite side respectively through on, following tube connector links with 214 oxyhydrogen generators that protrude hull outside, on last tube connector, be provided with safety valve, be fixed with on housing that combustion-supporting that electric cabinet forms realizes.

Described oxyhydrogen generator is that outside is provided with the reactor that metal shell that nozzle, inside be provided with catalytic media constitutes.

The beneficial effects of the utility model: this utility model is owing to taked the combination of said structure and each parts, make the catalytic media in the oxyhydrogen generator produce catalytic action by means of furnace temperature, the water that injects oxyhydrogen generator is resolved into hydrogen and oxygen fast, and under the internal pressure effect, directly spray into burner hearth through nozzle and participate in burning, combustion of hydrogen wherein, comburant oxygen.Walk abreast into the high flame of whirlwind and can make 1300 ℃ of stove Nei Wenduda, not only significantly improved fire box temperature, the holdup times in stove such as flue dust have obviously been prolonged, make the combustible in fuel and the flue dust obtain more fully burning, and effectively saved fuel source, increased substantially heating efficiency, obviously reduced dust emission, reliably realized goal of the invention.Have structural design compact and reasonable, stable and reliable working performance simultaneously, control advantages such as easy to use, that energy-conserving and environment-protective are economical and practical, be fit to widely popularize in the industry automatically.

Description of drawings:

Fig. 1 is an outline drawing of the present utility model;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the vertical view of Fig. 2.

The specific embodiment:, form by one or two combustion-supporting by Fig. 1-coal-burning boiler combustion-supporting shown in Figure 3.Combustion-supporting is to establish water tank 2 in housing 1, above water tank 2 one sides, be connected with blast pipe 4 through exhaust solenoid valve 3, the below is connected with water inlet pipe 7 through entering water electromagnetic valve 5, check-valves 6, link through three oxyhydrogen generators 10 of upper and lower tube connector 8,9 and protrusion housing 1 outside respectively at water tank 2 opposite sides, on last tube connector 8, be provided with safety valve 11, also be fixed with electric cabinet 12 on the housing 1.And oxyhydrogen generator 10 to be outsides be provided with nozzle 13, inside are provided with the reactor that the metal shell of catalytic media 14 constitutes.During assembling, open three or six holes suitable with oxyhydrogen generator 10 in the one or both sides of the corresponding water-cooling wall of coal-burning boiler, between oxyhydrogen generator 10 is built in water-cooling wall in the boiler from the hole, and this side housing 1 form a dividing plate with all parts in the housing 1 every outside coal-burning boiler.Another assembling mode is that the nozzle 13 on the corresponding oxyhydrogen generator 10 between the water-cooling wall of coal-burning boiler one or both sides is left three or six corresponding apertures, and inserts nozzle 13 in corresponding aperture.This kind assembling mode will ℃ can to oxyhydrogen generator 10 additional heat may to 300.

During the coal-burning boiler operation, connect working power of the present utility model, under electric cabinet 12 and water level controller control, open entering water electromagnetic valve 5 and exhaust solenoid valve 3 automatically, water enters water tank 2 through water inlet pipe 7, check-valves 6, entering water electromagnetic valve 5, and tube connector 9 is sent in three or six oxyhydrogen generators 10 under the warp.Air in the oxyhydrogen generator 10 is discharged from blast pipe 4 through exhaust solenoid valve 3.Oxyhydrogen generator 10 in burner hearth or the outside be heated, when temperature reached 300 ℃, water just resolved into hydrogen and oxygen under the effect of catalytic media 14, under pressure inside by nozzle 13 ejection.Walking abreast into cyclonic air flow burns.The water of water tank 2 is continuously sent into oxyhydrogen generator 10, and the maintenance of the water level of water tank 2 is by water level controller and entering water electromagnetic valve 5 automatic supplies.When last tube connector 8 pressure are excessive, unnecessary gas will be discharged from safety valve 11.Guarantee safety.
